Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
FIG. 1 is a schematic diagram of an implementation environment provided by embodiments of the present application. The implementation environment includes a server 110, a communication network 120, and a user terminal 130, where the user terminal 130 includes a first user terminal 131, a second user terminal 132, …, and an nth user terminal 13n, and the user terminal 130 may be connected to the server 110 through the communication network 120.
Optionally, the server 110 is a server, or is composed of several servers, or is a virtualization platform, or is a cloud computing service center, and the number and types of the servers 110 are not limited in this embodiment of the present application. The communication network 120 is a wired network or a wireless network, and the type of the communication network 120 is not limited in the embodiments of the present application. The user terminal 130 may be a mobile terminal device such as a tablet computer or may be a personal computer (Personal Computer, PC), such as a laptop portable computer and a desktop computer, etc. Those skilled in the art will appreciate that the number of user terminals 130 may be one or more, and the types may be the same or different. For example, the number of the user terminals 130 may be one, or the number of the user terminals 130 may be several tens, or more. The number and device types of the user terminals 130 are not limited in the embodiment of the present application.
In an alternative embodiment, each user may log onto the server 110 over the communication network 120 on a corresponding user terminal 130, such as by a browser or application program. Through the "collaboration" function on the electronic whiteboard, the electronic whiteboards on the screen of each user terminal 130 may be connected to each other through the communication network 120, and each user terminal 130 performs sharing of input elements through the server 110, so as to implement interactive use of the electronic whiteboards. For example, the user of the first user terminal 131 inputs a corresponding element on the electronic whiteboard, and the element can be transmitted to the server 110 through the communication network 120, and then the element is sent to the users of other user terminals through the server 110, so that sharing of the input element is realized. That is, each user terminal participating in the "collaboration" function can realize sharing of input elements with each other.
In one embodiment, the "collaboration" function of the electronic whiteboard may be divided into that the corresponding collaborators (i.e. the users of the user terminals) have the right to write or read, that is, when the user of one user terminal has the right to read only, the user of the user terminal can only see the write of the user of the other user terminal on the electronic whiteboard of the user terminal; when a user of a user terminal has the right to write, the user of the user terminal can write on the electronic whiteboard of the user terminal, and the write can be checked by the users of other user terminals.
Fig. 2 is a block diagram of an electronic whiteboard and navigation interface presented on a screen of a user terminal according to one embodiment of the present application. As shown in fig. 2, the screen 210 of the user terminal is an entire large rectangular frame, and the navigation interface 220 occupies a certain position of the screen 210 of the user terminal, for example, in the lower right corner of the screen 210 of the user terminal, but the embodiment of the present application is not limited thereto, and may be located in the lower left corner of the screen 210 of the user terminal, or the navigation interface 220 may be movable to move the navigation interface 220 to a place where the user input element is not blocked. A portion of the electronic whiteboard 230 occupies the entire screen 210 of the user terminal, but in fact a portion of the electronic whiteboard 230 is occupied by the navigation interface 220 (e.g., a portion of the electronic whiteboard 230 is in the lower right corner), wherein since the entire canvas size of the electronic whiteboard 230 is larger than the size of the screen 210, only a portion of the electronic whiteboard 230 is presented on the screen 210 of the user terminal, the user can present other portions of the electronic whiteboard 230 not presented on the screen 210 of the user terminal by dragging the electronic whiteboard 230.
The first elements entered by the user on the electronic whiteboard 230, such as five-star 241, six-star 242, and eight-star 243, may be presented in another form on the navigation interface 220, such as a small box 241', a large box 242', and a middle box 243'. The size and position of the first element entered on the electronic whiteboard 230 corresponds to the size and position of the different sized boxes presented on the navigation interface 220.
Fig. 3 is a flow chart of a method for presenting an electronic whiteboard according to an embodiment of the present application. The method described in fig. 3 is performed by a computing device, but the embodiments of the present application are not limited thereto. As shown in fig. 3, the method includes:
s301: at least part of the electronic whiteboard is presented in a first area of a screen of the first user terminal, and a navigation interface of the electronic whiteboard is presented in a second area of the screen, wherein the electronic whiteboard comprises at least one first element, and the navigation interface comprises at least one second element corresponding to the at least one first element.
In an embodiment, the first area of the screen is the area 230 as shown in fig. 2, at least part of the electronic whiteboard is presented on the first area, but the embodiment of the application is not limited to the specific canvas size of at least part of the electronic whiteboard, the canvas size of at least part of the electronic whiteboard presented on the first area depends on the size of the screen, that is, how large the size of the screen is, and at the same time, since the sizes of the first areas of the screens with different screen sizes are different, the canvas size of at least part of the electronic whiteboard presented is also different, for example, the size of the first area of the screen with a small screen size is smaller than the size of the first area of the screen with a large screen size, and then the canvas size of at least part of the electronic whiteboard presented also has such a size relationship. The second area of the screen is an area 220 as shown in fig. 2, on which a navigation interface of the electronic whiteboard is presented, but the embodiment of the present application is not limited to a specific position and a specific size of the second area on the screen, as long as the navigation interface does not obstruct the user from using the electronic whiteboard normally.
In another embodiment, the at least one first element included on the electronic whiteboard may be the elements 241 to 243 input by the user as shown in fig. 2, or may be other types of elements, which are not specifically limited in this embodiment, and meanwhile, the specific number of the at least one first element is not limited in this embodiment; the at least one second element included in the navigation interface corresponding to the at least one first element may be blocks 241 'to 243' as shown in fig. 2, or may be other types of elements, which are not specifically limited in this embodiment, and the specific number of the at least one second element is not limited in this embodiment.
In another embodiment, as described above, when the "collaboration" function of the electronic whiteboard is turned on, the user of the first user terminal may share elements with the users of other collaborative user terminals to present each user-entered element on the screen of the first user terminal. The "collaboration" function may be divided into a right of a corresponding collaborator having a write operation or a read operation, and the embodiment of the present application is not limited to a right of a collaborator of the first user terminal, which may have a write operation or a read operation, and the embodiment of the present application is not limited to this, and the embodiment of the present application also is not limited to a right of the first user itself, which may have a write operation or a read operation.
S302: and adjusting the display of the electronic whiteboard according to the operation of the first user terminal on the navigation interface aiming at the second element so as to present the first element corresponding to the second element on the first area.
In one embodiment, since the entire canvas size of the electronic whiteboard is greater than or equal to the size of the screen of the first user terminal, this is detrimental to the user to quickly locate the corresponding element on the electronic whiteboard when the element entered by the user on the electronic whiteboard is too dispersed or sufficiently numerous (as many elements beyond the screen of the first user terminal). For this purpose, the display of the electronic whiteboard may be adjusted according to an operation performed on the navigation interface by the first user of the first user terminal for the second element, so as to present the first element corresponding to the second element on the first area of the screen.
It should be noted that, the embodiment of the present application does not limit what operation is performed on the navigation interface by the first user of the first user terminal for the second element, as long as adjustment of display of the electronic whiteboard can be achieved. That is, since the position and size of the first element correspond to those of the second element, the user can navigate the first element by manipulating the second element on the navigation interface.
Therefore, no matter how large the whole canvas size of the electronic whiteboard is, the embodiment of the application can realize the navigation of the first element by operating the second element on the navigation interface, namely, the first element corresponding to the second element is presented on the first area of the screen, so that a user can quickly position the corresponding element on the electronic whiteboard, and further, the learning or working efficiency of using the electronic whiteboard by the user is improved.
In another embodiment of the present application, the at least one first element comprises a first element entered by a first user on the electronic whiteboard.
It should be noted that, the embodiment of the present application is not limited to the specific type of the first element input by the first user on the electronic whiteboard.
In one embodiment, as described above, when the "collaboration" function of the electronic whiteboard is turned off, the first user may navigate the first element entered by himself by operating on the second element at the navigation interface of the electronic whiteboard, while no other collaborators are engaged therein. When the 'collaboration' function of the electronic whiteboard is started, other user terminals can participate in the electronic whiteboard.
In another embodiment of the present application, the at least one first element further comprises a first element input by the second user on an electronic whiteboard of the second user terminal.
It should be noted that, the embodiment of the present application is not limited to the specific type of the first element input by the second user on the electronic whiteboard.
In one embodiment, as described above, when the "collaboration" function of the electronic whiteboard is turned on, a first user of the first user terminal may share input elements with a second user of the second user terminal to present the first element of each user input on the screen of the first user terminal. At this time, the first user may have the right of writing operation or the right of reading operation, that is, when the first user has the right of writing operation, the first user may navigate not only the first element input by the first user but also the first element input by the second user through the operation of the navigation interface on the electronic whiteboard; when the first user has only the right of the read operation, the first user can navigate the first element input by the second user only through the operation of the navigation interface on the electronic whiteboard, and cannot input the first element itself.
In another embodiment of the present application, the at least one first element includes a first element input by a first user on the electronic whiteboard and a first element input by a second user on the electronic whiteboard of the second user terminal.
It should be noted that the second user may refer to one user or may refer to a plurality of users, and the embodiment of the present application is not limited to a specific number of second users.
In another embodiment of the present application, the method further comprises: the first user terminal receives a first element input by a second user on an electronic whiteboard of the second user terminal from the server.
In an embodiment, after the second user inputs the first element on the electronic whiteboard of the second user terminal, the second user terminal may send the first element input by the second user to the server through the communication network, and after the server receives the first element input by the second user, the server may send the first element input by the second user to the first user terminal through the communication network, so as to present the first element input by the second user on the electronic whiteboard of the first user terminal.
In another embodiment of the present application, a navigation interface of an electronic whiteboard is presented on a second area of a screen, including: and according to the size proportion of the electronic whiteboard and the navigation interface, performing equal proportion conversion on the size and the coordinates of the first element to obtain the size and the coordinates of the second element, so that the second element can be displayed on the navigation interface conveniently.
In an embodiment, a size ratio between the size of the whole canvas of the electronic whiteboard and the size of the navigation interface is calculated, then the size and the coordinates of the first element are subjected to equal ratio conversion according to the size ratio of the electronic whiteboard and the navigation interface, and finally the size and the coordinates of the second element can be obtained, so that the second element can be displayed on the navigation interface.
The corresponding relation between the first element and the second element can be established by carrying out equal proportion conversion on the size and the coordinate of the first element to obtain the size and the coordinate of the second element, namely, each time the first element is input on the electronic whiteboard, the corresponding second element corresponding to the first element can be generated on the navigation interface, and the size and the coordinate position of the second element correspond to the size and the coordinate position of the first element. For example, as shown in fig. 2 above, the first element-five-pointed star 241 on the electronic whiteboard is located on the left side of the electronic whiteboard, the first element-octagon 243 is located on the upper side of the electronic whiteboard, and the size of the five-pointed star 241 is smaller than that of the octagon 243, so that the coordinate positions and sizes of the second element-small frame 241 'and the middle frame 243' presented at the navigation interface also correspond to those of the five-pointed star 241 and the octagon 243.
In another embodiment of the present application, the method further comprises: and determining a movable positioning frame for navigation at the navigation interface.
In an embodiment, to facilitate the first user of the first user terminal operating on the second element on the navigation interface, a movable positioning frame for navigation may be determined on the navigation interface. However, it should be noted that the embodiment of the present application is not limited to the specific shape and specific size of the movable positioning frame, as long as the first user of the first user terminal can operate on the second element on the navigation interface.
In another embodiment of the present application, adjusting, according to an operation performed on a navigation interface by a first user of a first user terminal for a second element, display of an electronic whiteboard to present, on a first area, the first element corresponding to the second element, includes: and navigating the first element in the first area according to the movable positioning frame and the second element so as to quickly present the first element on the screen of the first user terminal.
In an embodiment, the operation performed by the first user of the first user terminal on the navigation interface for the second element may refer to: the first user of the first user terminal selects the second element by moving the movable positioning frame, i.e. the second element framed in the movable positioning frame is the selected second element. Since the electronic whiteboard and the navigation interface are subjected to equal-scale conversion, the second element is selected by moving the movable positioning frame, so that the navigation of the first element in the first area can be realized, that is, no matter where the first element is located in the whole canvas of the electronic whiteboard, the first element corresponding to the selected second element can be quickly presented in the first area, so that the navigation of the first element in the first area can be realized.
In another embodiment, the size of the movable positioning frame is used to represent the size of the screen, that is, the size of the movable positioning frame is equal to the size of the screen, and by moving the movable positioning frame, the second element in the area same as the size of the screen can be selected, so that the first element corresponding to the second element is displayed in the first area, and thus the first element in the large area can be navigated more conveniently without limiting the navigation of the first element to only a few single first elements.
However, the size of the movable positioning frame is not limited in the embodiment of the present application, and the embodiment of the present application is not limited to the specific shape of the movable positioning frame, and the shape of the movable positioning frame may be rectangular, circular, trapezoid, or the like.
In another embodiment of the present application, the method further comprises: determining a canvas size of at least one first element on an electronic whiteboard, wherein determining a movable positioning frame for navigation at a navigation interface comprises: when the canvas size is greater than or equal to the size of the screen of the first user terminal, a movable positioning frame is obtained.
